A thermoplastic resin-silicone rubber composite shaped article comprising (a) a shaped article of a thermoplastic resin selected from the group consisting of soft vinyl chloride resins, olefin resins, urethane resins and styrene resins and (b) a cured layer of an addition polymerization type silicone rubber composition adhering to the one or both surfaces of the shaped article of a thermoplastic resin. To the surface of the above shaped article of a thermoplastic resin to which the above cured layer of an addition polymerization type silicone rubber composition does not adhere, there may adhere another cured layer of the above addition polymerization type silicone rubber composition. To either or both of these cured layers, there may further adhere a layer of the above thermoplastic resin, other thermoplastic resin, a silicone rubber, a silicone resin, glass, ceramics or a metal.
摘要:
A soft vinyl chloride resin-silicone composite shaped article consisting of a soft vinyl chloride resin shaped article and a cured layer of an addition polymerization type silicone composition adhered to the surface of the vinyl chloride resin shaped article, wherein said addition polymerization type silicone composition contains an organohydrogenpolysiloxane having at least two hydrogen atoms directly bonding with silicon atoms in each molecule, in an amount enough to provide one to six such hydrogen atoms per one vinyl group of the silicone composition. The above composite shaped article has a very high bonding strength between the vinyl chloride resin shaped article and the cured layer of an addition polymerization type silicone composition.

There is provided a catalyst for a water gas shift reaction in a hydrogen gas which is able to effectively remove CO in the hydrogen gas within a broader temperature range. Such a catalyst for the water gas shift reaction is characterized in that a metal oxide carrier supports at least platinum. The catalyst can be used for removing carbon monoxide in the hydrogen gas. Particularly, such a catalyst can be used in the water gas shift reaction for removing carbon monoxide in a reformed gas in a fuel cell generation system.

A floorboard 5 is supported on bridge gate shaped piers 2 so as to move horizontally by rollers 4 provided at the corners of the floorboard. Rubber members 7 installed between the floorboard 5 and the piers 2 restoring force to restitute elastically the floorboard to a neutral position when the floorboard moves horizontally. A shaker 8, which is fixed on the floorboard 5, excites the floorboard linearly and reciprocally by a weight 12 movable along a ball screen shaft 11 with a motor 10. The inertia force of the floorboard 5 generates, in a real-size and real-time scale, vibration for a main structure to which a vibration-controlling damper 15 is installed. The vibration of the floorboard 5 is inputted to the damper 15 and the dynamic response of the damper is observed by a computer 14.
摘要:
In a fire alarm system one of a fire receiver and terminal devices transmits the same signals in opposite transmission directions to first and second loop-signal lines. The remaining ones of the fire receiver and terminal devices receive the signals transmitted through the first and second loop-signal lines and detect whether there is an abnormality in transmission by detecting differences in the receiving times of the signals. Consequently, an abnormality of transmission is detected immediately. A fire receiver or terminal device which detects any abnormality immediately causes the first and second loop-signal lines connected with each other to form a signal loop-back path, thereby transmitting signals to the entire loop-signal line except to the position where the abnormality occurs. As a result, the reliability of signal transmission is significantly improved.

The present invention provides a catalyst for steam reforming of hydrocarbons which comprises ruthenium supported on a zirconia carrier; and a catalyst for steam reforming of hydrocarbons which comprises (A) at least one element selected from the group consisting of rhodium and rutheniuim as an element imparting mainly reforming activity and (B) at least one element selected from the group consisting of nickel, lanthanum, praseodymium, neodymium, samarium, thorium, uranium, chromium, magnesium, calcium, and yttrium as an element for imparting co-catalyst function which are supported on a zirconia carrier; and furthermore a catalyst for steam reforming of hydrocarbons which comprises at least one element selected from the group consisting of rhodium and ruthenium which is supported on a partially stabilized zirconia carrier.
摘要:
A thermal printer wherein a sheet of recording paper is interposed between two drums provided on axially opposite sides of a shaft of a platen roll facing a line-type thermal head and an endless belt mounted on outer peripheries of the drum. One way clutches provided on a shaft of the drum will cause the paper to rotate together with the drums during recording and the recording paper is driven by the endless belt during paper feed and delivery operations to slide relative to the drums. The sheet of paper is fed to a lower portion of an open portion of the drums and is removed from an upper portion of the open portion of the drums so that the feed and delivery of the sheet of paper can be effected upon rotation of the drums in one direction, and the printing operation is started after a detection of a trailing end of the sheet of paper so that the printing operation can be reformed regardless of the length of the sheet of paper immediately after the feed of the sheet of paper.
摘要:
A heat-sensitive recording material is disclosed. The material comprises a support having provided thereon a heat-sensitive color-forming layer containing a colorless or slightly colored electron donating dye precursor and an electron accepting compound which is capable of forming color by reaction with the said electron donating dye precursor, wherein said color-forming layer has provided thereon a protective layer containing a binder and said color-forming layer contains a hardening agent which is capable of hardening said binder in the protective layer by reaction with said binder.
